Can I use the Xian Public Transportation Card for going by bus to the Terracotta Warriors?

You can buy the card at the metro station in the north railway station.

Do you go to the Terracotta Warriors from the north railway station? If yes, you can first take the metro line 2 to City Library and then get on the bus No.230 or Tourism No.10. Then get off at Huaqing Lijiao East to take the bus 915 to the scenic area. You can take the buses with your card.
